Description

Selection
No.
- / uint16
Activates/deactivates the DC hold and
post-magnetization functions. See section
Note:
•
DC hold is only available with speed control in DTC
motor control mode (see page
•
DC magnetization causes the motor to heat up.
In applications where long DC magnetization
times are required, externally ventilated motors
should be used. If the DC magnetization period is
long, DC magnetization cannot prevent the motor
shaft from rotating if a constant load is applied
to the motor.

1 = Enable DC hold. See section
.
Note: The DC hold function has no effect if the start
signal is switched off.
DC hold

1 = Enable post-magnetization. See section
Note: Post-magnetization is only available when
ramping is the selected stop mode (see parameter
